<h3>
Answer: $111.11</h3>
=======================================================
Explanation:
Let's say you earn x dollars.
You pay 10% tax on that, which means you pay 0.10x dollars.
This would drop to x-0.10x = 0.90x which is the amount earned after tax.
So you pay 10% of what you earn, and keep 90% of the rest.
Set this equal to the target $100 you want and solve for x.
0.90x = 100
x = 100/0.90
x = 111.11
Notice that 10% of this is 0.10*x = 0.10*111.11 = 1.11 when rounding to the nearest penny. So you'll pay $1.11 in tax. Therefore, you'd have x-0.10x = 111.11 - 1.11 = 100 left over. So the answer checks out.
Answer:
a. 4
Step-by-step explanation:
-1(-4) = 4
The level from each growth factors is an illustration of combination
There are 90 ways of combining one level from each growth factors
<h3>How to determine the number of combination</h3>
From the complete question (see attachment), we have the number of levels in each growth factor is:
- Lighting = 3
- Age = 5
- Temperature = 2
- Humidity = 3
So, the number of combination (n) is:
n = 3 * 5 * 2 * 3
n = 90
Hence, there are 90 ways of combining one level from each growth factors
